To assess the pattern of ColoAd1 viral delivery and viral expression within colon tumour tissue when administered by intra-tumoural injection or within colon, non-small cell lung, bladder and renal cell tumour tissues following ColoAd1 administration by intravenous infusion.
Composite measure of viral delivery and spread [ Time Frame: Up to Day 25 ]
To assess the pattern of viral delivery and viral spread of ColoAd1 within tumour tissue when administered either by intra-tumoural injection or by intravenous infusion. Viral delivery and spread will be measured by immunohistochemical staining for ColoAd1 in tumour sections taken from patients. Presence of virus will also be detected by qPCR analysis of tumour tissue.
